However, they’re not necessarily inedible. Green beans with brown spots may indicate that the beans are beginning to spoil or that they have been damaged in some way. Do Brown Spots Mean The Beans Are Inedible? Since I often consume home-grown green beans, it’s good to keep an eye out for potential symptoms of diseases. If you’re just getting your green beans from the fresh produce aisle in the supermarket, this isn’t something you should worry about. However, this is only relevant if you’re growing your own veggies. If your green bean plants are impacted by these diseases, it’s always best to remove the affected plants to prevent the disease from spreading throughout the crop. Like the previous disease, a more severe case involves discovered or brownish beans. A severe case of this virus causes the green beans to become discolored or even to turn brown.Īnthracnose, on the other hand, is a fungal disease that can also be characterized by dark, sunken lesions on the leaves, stems, and pods of the plant. Not many people have heard about this, but the bean mosaic virus or anthracnose are diseases that can also cause your green beans to turn brown, and they may also cause the leaves of the plant to wilt and die. If you’re growing your own green beans (like I sometimes do), you want to pay attention to signs of disease.įor instance, the symptoms of bean mosaic virus (BMV) can include yellow or brown mottling or mosaic patterns on the leaves, stunted or distorted growth, and reduced yields. These pests can damage the beans by feeding on their plant tissue and injecting toxins that lead to a quicker breakdown of the cells and consequently, a more rapid development of brown spots and eventually rot. Pest infestations such as by aphids or thrips can also cause green beans to develop brown spots. Another factor that also accelerates this process is bruising or rough handling, though the brown spots tend to be more localized, so it’s generally fine to eat the beans as long as you remove the brown parts. These factors accelerate the natural breakdown of cells inside the beans, causing them to develop brown spots over time. Green beans also turn brown from being far too exposed to heat, sunlight, or air. This is a natural process that transpires with every vegetable, but it doesn’t necessarily mean that the green beans are spoiled or inedible, unless it’s accompanied by other signs of spoilage. Unfortunately, as the beans lose moisture and nutrients over time, they begin to develop yellow and brown spots, a process that occurs because the cells inside the beans break down and the pigments that give them their green color start to fade. Green beans may develop brown spots for several reasons- the most common being aging. What Causes Brown Spots In Green Beans? Home-grown green beans (Photo: Vegan Foundry) In this article, I’ll go over the several reasons why green beans may develop brown spots, when to avoid them, and how to store them properly to prevent them from spoiling. If the brown spots are small and limited to a few beans you can remove the affected areas and still consume them. Found a bag of green beans with a few brown spots in the grocery store, or maybe spotted some brown spots on your fresh green beans when preparing them for dinner?įortunately, green beans with brown spots are safe to eat as long as they’re not accompanied by other signs of spoilage such as an off smell, sliminess, or a soft or mushy texture.
